Definitions
- the hub assembly 10 shown in Fig. 1 includes a main housing 11 which defines a hollow body 12 having an open top 13 and an open bottom 14.
- the housing 11 has a skirt 15 and a tapered shoulder 16 which are adapted to engage the inner surface of a roulette wheel assembly.
- An axle 17 located within the body 12 is axially supported by an upper ceramic bearing 18 which is positioned in the open top 13 that is closed by a plug 19 and a lower ceramic bearing 20 positioned in the bearing housing 21 that is a press fit in the open bottom 14 of the body 12.
- the mechanical device consists of the housing 11 and the axle 17 which is supported by the ceramic bearings 18 and 20 which prevents any axial contact between the inner disc magnet 27 and the outer ring magnet 28.
- This arrangement allows the forces needed to separate an inner disc from an outer ring (axially) to be cumulative or in series - that is, if the force to separate one magnetic disc from its associated ring is say 20 kg then the force needed to separate the stack of four magnetic discs of Fig. 5 is four times that or 80 kg.
